FISHER保卫阀164/164A系列产品介绍
Introduction
The Types 164 and 164A switching valves are pneumatically operated and controlled units, built with a wide range of capabilities to handle those switching application that involve venting, on-off control, and failure modes.
Operation of either valve occurs when the pneumatic signal changes as indicated in table 1. With its two ports, the Type 164 switching valve is typically used as a normally open on-off switch, while the Type 164A switching valve directs flow through three ports. Additionally, the Type 164A provides on-off capability when one of its three port is plugged.
The Type 164 and 164A switching valves share the same basic construction (see figures 1 and 2), except that where the Type 164A switching valve has a part containing port B, the Type 164 switching valve has a plug.
Features
• Versatile—Constructions throughout the product line provide three-way or on-off pneumatic switching to suit a variety of applications.
• Easy, Accurate Adjustment—With a choice of springs for optimum resolution, the switching point is set to a specific requirement by an adjusting screw atop the spring case.
• Rugged, Compact Construction—The unit is small enough for easy installation in limited space, yet rugged enough to be mounted on the actuator.
164和164A型切换阀是气动控制单元，具有多种功能，可以处理涉及排气，开/关控制和故障模式的切换应用。
如表1所示，当气动信号发生变化时，任一阀都会发生操作。164型切换阀具有两个端口，通常用作常开开关，而164A型切换阀则通过三个端口引导流量。此外，插入三个端口之一时，164A型可以提供开关功能。
164型和164A型切换阀具有相同的基本结构（见图1和2），不同之处在于164A型切换阀的一部分包含端口B，而164型切换阀具有一个塞子。
特征
•多功能性—整个产品线的结构均提供三向或开关式气动开关，以适应各种应用。
•简单，准确的调节-通过选择弹簧以获得最佳分辨率，可通过弹簧盒顶部的调节螺钉将开关点设置为特定要求。
•坚固，紧凑的结构-该单元足够小，可以在有限的空间内轻松安装，但坚固到足以安装在执行器上。
